Application filed January 26, 1926. Serial No. 83,899.

My invention relates to oil burners for heaters and while itis of very general ap plication to various types of oil heaters, it has, "for reasons which will appear, an especial utility with water heaters and will therefore be illustrated and described as enrbodied in such aheater.

In the usual portable heater of the oil burning type, the upper or drum part may hinge to the base to afford access to the burnerfor cleaning and repairing andrewiclting, but in some forms of heaters it is not practicable to so hinge the drum to the base. For examplain water heaters the connection of the coils in the heaterto the water inlet and outlet conduits requires that the heater be stationary and that the casing beimmovable relative to the base.

One purpose of my invention is to provide means whereby the burner may be made readily accessible in heaters of the type where the upper part is not. hinged to the base, and my invention contemplates mounting (the burner upon a swinging base .Or

-'- support which is so hinged to the heater base that the burner is brought clear of the base when the support isswung out.

The burner extends from its support up through an opening in the bottom of'the casing. In order to permit the burner to be swung out of the casing the front section of the casing is made removable, and the front of the base is also open. In order that the device may be made to open either to the right or left. depending upon the requirements of its location, I have. in accordance with my inventiom'provided a hinge construction both for the front section of the casing and for the burner support which permits these parts to be swung either, way. My invention also includes means for permitting the oil pipeto be reversed with re spect to the burner base so as tobring the oil reservoir or supply tank on either side of the heater. My invention has other objects and advantages and comprehends various other details and arrangements of parts. as will hereinafter more fully appear.

I shall now describe the illustrated embodiment of my invention and shall thereafter point-out my invention in claims. Fig. 1 is a central vertical section through embodying myinvention; trout of the same;

Fig. 6 is a-transverse section through the heater on the line 66 of'Fig. 1;

Fig. 7 is a transverse seetionfthrough the base on the line 7-7 of Fig. 2.

The invention is illustrated inua -water heater, the main casing 1 of which iscylindrical and has its front; section 52,- w-hich is substantially half the casing, hinged to open. The lower manifold 3,wl1ichispreferably of brass, is oval in shape, as shown in Fig. 5,

and is provided at its outer end with a collar or bushing portion 4 which isnon-ciroul-ar in shape and fits in a seat in a boss 5 on the wall of the casing. This prevents the manifold from turning when the heater is being erected. A. nut 6 screws on the outer thread ed end of the manifold which protrudes through the casing and this nut bears against the outer face of the casing and locks themani-fold in place. The inlet pipe 7 is screwed into this manifold.

The upper manifold 8 is oblong, as appears in Fig. 3, and. also has a non-circular collar or bushing 9, corresponding to the" bushing a, and fitting into a seat in aboss 10 in thewall fof/the casing. locks the manifold 8 in its seat'in the casing. in thesame way that .the nut 6 looks the" lower manifold in place. The hot water or outlet pipe 12 screws. into *themanifold *8. There are shown four water coils which connect zit-their bottom ends with four openings ingthe cold water manifold 3, and at their upper ends with four openings in the upper manifold 8. Qbviously, the number otthese coils may be varied according'to requirements. ,They will preferably be .arranged in staggered relati-on so that each turn is over a space between two adjacent coilsimmediately below. In this 'way -the hot gases have free access to all the turns of the water coils.

A pipe collar 14 is secured to the'back section 1 of the casing, and this leaves the front section: *2" free to open and 'ciosewith e t-23 interfering; withthe pipe "eollan itt The .nut 11 f transparent window 15 of mica or other suitable material is secured in a frame in the front section in proper location to afford observation to the flame.

The construction and arangement of the water coils and associated parts as shown and as above described, form no part of my present invention but are described and claimed by me in a copending application, Serial No. 148, 648, filed November 16. 1926. Any suitable type of burner may be used with the device, but I have shown a burner 16 of the type known as the blue flame burner which requires a long chimney or casing to induce the necessary draft to make the burner operate properly. In the heater shown, the casing 1 serves as the chimney. The spaces between the co ls 15 will be sufiicient to allow a free circulation so as not to interfere with the draft.

The burner is mounted upon a swinging support 17 hinged to the base portion 1 of the casing 1, and the burner extends with its upper end into the bottom of the casing 1 in sufliciently close proximity to the manifold 3. The bottom of the casing is constructed with an integral inward flange or shoulder so as to provide a burner opening 18 only slightly larger than the burner. This leaves a narrow annular space about the burner collar for the passage of air and this construction also prevents the distortion or misplacementof the burner 16 by the improper fitting of the two sections 1 and 2 of the casing.

The base section 1 of the casing is shown as substantially semi-circular. The swinging burner support 17 is shown as a circular plate or pan, the center of which is depressed and will catch any drippings from the burner. Extending substantially diametrically across the top of this pan l7 and secured thereon by clamps 19 is the oil pipe 20 which connects to an oil supply tank or reservoir (not shown), which is carried on the end of the pipe. A cap 20 closes the other end of the oil pipe outside of the heater base. The clamps 19 are shown as U-shaped clips with their ends turned outwardly, one end being inserted through a slit in the top of the pan 17 and the other end being secured by a screw, or otherwise. to the top of the pan. These clips extend over flattened sections of the oil pipe 20. and the burner 16 is secured on these flattened sections in the usual and well known way.

set screw 21" which is turned down and bears on top of the respective foot 16 of th burner.

The burner base or pan 1? is releasalily hinged to the outside of the base 1" on both sides of the open front. Each side of the base is provided with two hinge sections 23 and 23, while on opposite sides of the pan 1? are provided a hinge section 24 which is formed on the outer side of an integral arm 25 extending outwardly so as to bring the hinge section in cooperative relation with the sections 22 and 23. Removable hinge pins or pintles Qti are provided for each hinge. lVhen the burner is in place, both hinge pins 26 are inserted and the swinging burner support 17 is locked against movement. Either pin 26 may be removed, according to the direction it: is desired to swing the support to provide access to the burner, the other pin then serving the pivot pin. Lugs 27 on the inside of the base serve to guide and position the burner support 17.

In order to permit the burner to be swung out it is necessary that the front section 2 of the casing he opened. For this purpose this section is shown as also hinged releasahly on both sides of the casing so as to allow it to be swung in the same direction that the burner is swung. This is oftentimes necessary as by reason, for example, of the location of the heater in a corner. The hinges 28 on the one side are provided with removable pins 29, and the hinges 30 on the other side are provided with removable pins 31.

In order to permit the heater to he set up with the oil supply tank on either side of the heater, the connection of the oil pipe 20 to the burner support 17 is such as to allow the pipe to be reversed. The clips 19 are taken out and this releases the oil pipe from the hinged support. The lHII'Ill! also will be reversed on the pipe in case of a reversal of the pipe, so as to keep the wick-adjusting member 32 on the outer side of the burner where it is accessible. This merely requires letting up on the set screws 21 until the burner feet 16 are free. and the straps 21 are then moved out and the burner turned around and the straps then brought back and the set screws again turned down.

It is obvious that various modifications may he made in the details and arrangements of parts herein described and illustrated for the purpose oi explainin g the nature of the invention within the prin iple and scope of the invention as expressed in the appended claims.
